President's Letter

Dear Shareowner,

Stock and bond markets around the globe have been experiencing one of their
most tumultuous periods in history. Investors have witnessed volatility of a
magnitude that many have never before seen. Distance often provides the best
vantage point for perspective. Still, we believe that the benefits of basic
investment principles that have stood the test of time -- even in the midst of
market turmoil -- cannot be underestimated.

First, invest for the long term. The founder of Pioneer Investments, Philip L.
Carret, began his investment career during the 1920s. One lesson he learned is
that while great prosperity affords an advantageous time for selling stocks,
extreme economic slumps can create opportunities for purchase. Indeed, many of
our portfolio managers, who follow the value-conscious investing approach of
our founder, are looking at recent market conditions as an opportunity to buy
companies whose shares we believe have been unjustifiably beaten down by
indiscriminate selling, but that we have identified as having strong prospects
over time. While investors may be facing a sustained market downturn, we
continue to believe that patience, along with staying invested in the market,
are important considerations for long-term investors.

A second principle is to stay diversified across different types of
investments. The global scope of the current market weakness poses challenges
for this basic investment axiom. But the turbulence makes now a good time to
reassess your portfolio and make sure that your investments continue to meet
your needs. We believe you should work closely with your financial advisor to
find the mix of stocks, bonds and money market assets that is best aligned to
your particular risk tolerance and investment objective.

As the investment markets sort through the continuing crisis in the financial
industry, we are staying focused on the fundamentals and risk management. With
more than 80 years of experience behind us, we have learned how to navigate
turbulent markets. At Pioneer Investments, risk management has always been a
critical part of our culture -- not just during periods of extraordinary
volatility. Our investment process is based on fundamental research,
quantitative analysis and active portfolio management. This three-pillared
process, which we apply to each of our portfolios, is supported by an
integrated team approach and is designed to carefully balance risk and reward.
While we

see potential chances for making money in many corners of the market, it takes
research and experience to separate solid investment opportunities from
speculation.

We invite you to learn more about Pioneer and our time-tested approach to
investing by consulting with your financial advisor or visiting us online at
www.pioneerinvestments.com. Thank you for investing with Pioneer.

Sincerely,


/s/ Daniel K. Kingsbury

Portfolio Management Discussion | 6/30/09

The first half of 2009 was a volatile period for real estate investments, as
the global recession, deteriorating credit markets, rising unemployment and
waning investor sentiment weighed heavily on the sector, particularly in the
early months of the period. The Federal Reserve Board (the Fed) and the U.S.
Treasury have injected an unprecedented amount of liquidity into the financial
system to stabilize the financial markets, but business sentiment remains
tentative in spite of a strong rally in the spring of 2009. In the following
interview, Matthew Troxell of AEW Capital Management, L.P., the Fund's
subadviser, discusses his strategies for managing the Fund amidst such
uncertainty during the six months ended June 30, 2009.

Q  Why did real estate investments struggle during the six months ended June 30,
   2009?

A  Deteriorating property fundamentals, the dearth of third-party commercial
   mortgage capital, the higher cost of available debt, and tightened lending
   standards put a damper on commercial real estate transactions, which, in
   turn, depressed property valuations. Consequently, real estate investments,
   as measured by the Morgan Stanley Capital International (MSCI) U.S. REIT
   Index, fell by 35% in the first two months of 2009.

   However, with the announcement of more well-defined government initiatives
   and more encouraging economic news in the spring of 2009, investor
   sentiment shifted into a more adventuresome, bargain-hunting mode --
   sharply driving up prices of investments previously shunned in the flight-
   to-quality market contraction of late 2008/early 2009. As a result, real
   estate securities rebounded during the second quarter of 2009, gaining a
   record 30%, according to the MSCI U.S. REIT Index, from April 1 through
   June 30. The real estate sector also benefited from gains in the financial
   sector and new equity issuance activity, which helped to improve the
   financial condition of several real estate investment trusts (REITs) and
   reverse some of the negative sentiment toward the real estate sector. U.S.
   REITs raised $14 billion in 48 offerings through June 30, 2009, far
   exceeding the amount of equity raised in all of 2008.

Q  How did the Fund perform for the first half of 2009?

A  For the six months ended June 30, 2009, the Fund's Class A shares posted a
   total return of -9.73% at net asset value, compared with a -12.43% return
   for the Fund's benchmark, the MSCI U.S. REIT Index. During the same period,
   the average return of the 239 real estate funds tracked by Lipper, Inc. was
   -9.52%. The Fund's outperformance of the MSCI U.S. REIT Index


4    Pioneer Real Estate Shares | Semiannual Report | 6/30/09


   largely was attributable to effective stock selection, particularly in the
   industrial, regional mall, and office sectors.

Q  Which holdings had the most impact on the Fund's performance during the six
   months ended June 30, 2009?

A  Investments in the office REIT Kilroy Realty, which was vulnerable to
   struggling markets in Southern California, and shopping center REIT Kite
   Realty Group, which is exposed to developments in Florida, detracted from
   the Fund's performance. We continue to believe the companies represent
   solid values relative to their peers and are maintaining overweight
   positions in both stocks. On the positive side, regional mall REIT The
   Macerich Company; office company DuPont Fabros Technology; and industrial
   REIT Liberty Property Trust were the top Fund performers over the six-month
   period. Our decision to overweight positions in those companies magnified
   the impact of their performance on the Fund's results.

Q  Could you describe the health of the various property sectors in which the
   Fund is invested?

A  Despite economic indicators suggesting that the economy could bottom out
   before the end of 2009, property-market fundamentals continue to
   deteriorate. In the retail sector, property vacancies have been climbing
   quickly. While consumer confidence has improved somewhat in recent months,
   consumers remain very cautious, and retail spending likely will recover
   quite slowly. Office property vacancies are rising nearly everywhere as a
   result of weak demand. Markets that are closely tied to the fortunes of
   financial employers have been particularly hard hit. While downtown
   vacancies were slow to rise, conditions have been deteriorating nearly as
   quickly as suburban markets since the middle of 2008. Within the
   industrials sector, availability rates are at record levels and show few
   signs of improving.

   The apartment sector has been influenced by crosswinds in the single-family
   housing sector. Rising foreclosures and stricter underwriting standards are
   pushing some home buyers and would-be buyers into the renters market.
   Conversely, rentals of investor-owned homes and condominiums are offering
   housing alternatives to would-be renters. The conditions likely will
   prevail until the single-family sector stabilizes. While the pace of home
   price declines has begun to slow, prices are likely to continue declining
   well into 2010, and perhaps later.

   In the hotel sector, occupancies were down by more than 10% in spring 2009,
   compared with one year earlier. Previously resilient room rates were also
   down markedly, so revenue per available room (RevPAR) is down by more than
   20%. Luxury hotels have been particularly hard hit. While hotel
   fundamentals should show rapid improvement when the economy recovers due to
   the night-to-night nature of their leases, RevPAR is likely to remain


                   Pioneer Real Estate Shares | Semiannual Report | 6/30/09    5


   under pressure as long as both leisure and business customers continue to
   limit travel.

Q  Given the fallout in the subprime mortgage market, do you anticipate a
   similar correction in the commercial real estate market?

A  Commercial real estate markets are indeed a risk factor for both lenders and
   the broader economy, because they did not begin to deteriorate until the
   subprime crisis was well under way. At a minimum, they likely will be a
   drag on the economic recovery that we expect to begin before the end of
   2009. For commercial real estate, a loss in jobs and income, wavering
   consumer and business confidence and increasing levels of indebtedness have
   caused many commercial real estate tenants to postpone expansion plans,
   delay leasing decisions and, in some cases, close entirely. Real estate
   will not begin to see improving fundamentals until well after other sectors
   have begun to grow. The bottom line is that for real estate, jobs matter.
   Jobs fill office space, create the income that pays apartment rents, allow
   consumers to spend money at retailers, and ultimately drive demand for
   shipping, transportation and warehouse space.

   Moreover, the credit crisis has made it difficult for property owners to
   get the capital they need to weather the downturn. Owners unable to get
   that capital will need to enter difficult negotiations with lenders in
   order either to restructure loans or, in extreme cases, give the keys to
   the lenders and walk away from their equity investment. In addition to lost
   real estate equity, such outcomes introduce even more stress to already
   overburdened lending markets, and in doing so could put the entire recovery
   at risk.

   While such risks should not be understated, most observers do believe that
   the economy will emerge from the recession and into a modest recovery
   sometime during the next few quarters. Policymakers are making
   unprecedented efforts to stimulate the economy and heal credit markets, and
   while many economic indicators are still at recessionary levels, they have
   shown substantial improvement in recent months. Due to the difficulty in
   financing construction projects, new supply is not a concern in most
   property markets. While we believe real estate fundamentals will continue
   to deteriorate for some time, a growing economy would do much to put a
   floor under the commercial real estate sector and prevent it from dragging
   the broader economy back into recession.

Q  What is your outlook for the Fund for the balance of 2009?

A  The REIT sector has benefited in recent months from overall gains in the
   broader equities markets, due to optimism that the worst of the recession
   may be past. However, we do expect that REITs will continue to face some
   stiff headwinds in the coming months. Underlying real estate fundamentals
   remain challenged, unemployment remains at high levels, and company


6    Pioneer Real Estate Shares | Semiannual Report | 6/30/09


   earnings likely will remain muted in the near term. Furthermore, REIT
   pricing could be subject to further bouts of volatility, which will
   continue to be influenced by conditions in the global financial and credit
   markets. We'll remain vigilant in our securities selection within each
   sector to find the companies that we feel may provide the Fund with the
   best relative values and risk-adjusted returns.


Please refer to the Schedule of Investments on pages 16-19 for a full listing
of Fund securities.

The Fund invests in REIT securities, the value of which can fall for a variety
of reasons, such as declines in rental income, fluctuating interest rates, poor
property management, environmental liabilities, uninsured damage, increased
competition, or changes in real estate tax laws. At times, the Fund's
investments may represent industries or industry sectors that are interrelated
or have common risks, making it more susceptible to any economic, political, or
regulatory developments or other risks affecting those industries or sectors.

Past performance is no guarantee of future results, and there is no guarantee
that market forecasts discussed will be realized.

month-end performance results. Current performance may be lower or higher than
the performance data quoted.

The performance data quoted represents past performance, which is no guarantee
of future results. Investment return and principal value will fluctuate, and
shares, when redeemed, may be worth more or less than their original cost.

NAV results represent the percent change in net asset value per share. Returns
would have been lower had sales charges been reflected. POP returns reflect
deduction of maximum 5.75% sales charge. All results are historical and assume
the reinvestment of dividends and capital gains. Other share classes are
available for which performance and expenses will differ.

Performance results reflect any applicable expense waivers in effect during the
periods shown. Without such waivers Fund performance would be lower. Waivers
may not be in effect for all funds. Certain fee waivers are contractual through
a specified period. Otherwise, fee waivers can be rescinded at any time. See
the prospectus and financial statements for more information.

The performance table and graph do not reflect the deduction of fees and taxes

Comparing Ongoing Fund Expenses

As a shareowner in the Fund, you incur two types of costs:

(1) ongoing costs, including management fees, distribution and/or service
    (12b-1) fees, and other Fund expenses; and

(2) transaction costs, including sales charges (loads) on purchase payments.

This example is intended to help you understand your ongoing expenses (in
dollars) of investing in the Fund and to compare these costs with the ongoing
costs of investing in other mutual funds. The example is based on an investment
of $1,000 at the beginning of the Fund's latest six-month period and held
throughout the six months.


Using the Tables
- --------------------------------------------------------------------------------
Actual Expenses


The first table below provides information about actual account values and
actual expenses. You may use the information in this table, together with the
amount you invested, to estimate the expenses that you paid over the period as
follows:

(1) Divide your account value by $1,000
    Example: an $8,600 account value [divided by] $1,000 = 8.6

(2) Multiply the result in (1) above by the corresponding share class's number
    in the third row under the heading entitled "Expenses Paid During Period"
    to estimate the expenses you paid on your account during this period.

Hypothetical Example for Comparison Purposes

The table below provides information about hypothetical account values and
hypothetical expenses based on the Fund's actual expense ratio and an assumed
rate of return of 5% per year before expenses, which is not the Fund's actual
return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.


You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the
5% hypothetical examples that appear in the shareholder reports of the other
funds.

Please note that the expenses shown in the tables are meant to highlight your
ongoing costs only and do not reflect any transaction costs, such as sales
charges (loads) that are charged at the time of the transaction. Therefore, the
table below is useful in comparing ongoing costs only and will not help you
determine the relative total costs of owning different funds. In addition, if
these transaction costs were included, your costs would have been higher.

Notes to Financial Statements | 6/30/09 (unaudited)

1. Organization and Significant Accounting Policies

Pioneer Real Estate Shares (the Fund) is a Delaware statutory trust registered
under the Investment Company Act of 1940 as a diversified, open-end management
investment company. The investment objective of the Fund is to seek long-term
growth of capital. Current income is a secondary objective.

The Fund offers four classes of shares - Class A, Class B, Class C, and Class Y
shares. Each class of shares represents an interest in the same portfolio of
investments of the Fund and has identical rights (based on relative net asset
values) to assets and liquidation proceeds. Share classes can bear different
class-specific fees and expenses such as transfer agent and distribution fees.
Differences in class-specific fees and expenses will result in differences in
net investment income and, therefore, the payment of different dividends by
each class. The Amended and Restated Declaration of Trust of the Fund gives the
Board the flexibility to specify either per share voting or dollar-weighted
voting when submitting matters for shareholder approval. Under per share
voting, each share of a class of the Fund is entitled to one vote. Under
dollar-weighted voting, a shareholder's voting power is determined not by the
number of shares owned, but by the dollar value of the shares on the record
date. Share classes have exclusive voting rights with respect to matters
affecting only that class, including with respect to the distribution plan for
that class. There is no distribution plan for Class Y shares. Class B shares
convert to Class A shares approximately eight years after the date of purchase.

The Fund's financial statements have been prepared in conformity with U.S.
generally accepted accounting principles that require the management of the
Fund to, among other things, make estimates and assumptions that affect the
reported amounts of assets and liabilities, the disclosure of contingent assets
and liabilities at the date of the financial statements, and the reported
amounts of income, expenses and gains and losses on investments during the
reporting period. Actual results could differ from those estimates.

Because the Fund may invest a substantial portion of its assets in Real Estate
Investment Trusts (REITs), the Fund may be subject to certain risks associated
with direct investments in REITs. REITs may be affected by changes in the value
of their underlying properties and by defaults of their borrowers or tenants.
REITs depend generally on their ability to generate cash flow to make
distributions to shareowners, and certain REITs have self-liquidation
provisions by which mortgages held may be paid in full and distributions of
capital returns may be made at any time. In addition, the performance of a REIT
may be affected by its failure to qualify for tax-free pass through of income
under


28    Pioneer Real Estate Shares | Semiannual Report | 6/30/09


the Internal Revenue Code or its failure to maintain exemption from
registration under the Investment Company Act of 1940. The Fund's prospectuses
contain unaudited information regarding the Fund's principal risks. Please
refer to those documents when considering the Fund's risks.

The following is a summary of significant accounting policies followed by the
Fund in the preparation of its financial statements, which are consistent with
those policies generally accepted in the investment company industry.


A. Security Valuation

   Security transactions are recorded as of trade date. The net asset value of
   the Fund is computed once daily, on each day the New York Stock Exchange
   (NYSE) is open, as of the close of regular trading on the NYSE. In computing
   the net asset value, securities are valued at the last sale price on the
   principal exchange where they are traded. Securities that have not traded on
   the date of valuation, or securities for which sale prices are not generally
   reported, are valued at the mean between the last bid and asked prices.
   Securities for which market prices and/or quotations are not readily
   available are valued using fair value methods pursuant to procedures adopted
   by the Board of Trustees. Trading in foreign securities is substantially
   completed each day at various times prior to the close of the NYSE. The
   values of such securities used in computing the net asset value of the Fund's
   shares are determined as of such times. The Fund may also use fair value
   methods to value a security, including a non-U.S. security, when the closing
   market price on the principal exchange where the security is traded no longer
   reflects the value of the security. At June 30, 2009, there were no
   securities that were valued using fair value methods (other than securities
   valued using prices supplied by independent pricing services). Temporary cash
   investments are valued at cost which approximates market value.

   Dividend income is recorded on the ex-dividend date, except that certain
   dividends from foreign securities where the ex-dividend date may have passed
   are recorded as soon as the Fund becomes aware of the ex-dividend data in the
   exercise of reasonable diligence. Interest income is recorded on the accrual
   basis.

   Gains and losses on sales of investments are calculated on the identified
   cost method for both financial reporting and federal income tax purposes.


B. Federal Income Taxes

   It is the Fund's policy to comply with the requirements of the Internal
   Revenue Code applicable to regulated investment companies and to distribute
   all of its taxable income and net realized capital gains, if any, to its
   shareowners. Therefore, no federal income tax provision is required. Tax
   years for the prior three fiscal years remain subject to examination by tax
   authorities.


                  Pioneer Real Estate Shares | Semiannual Report | 6/30/09    29


   The amounts and characterizations of distributions to shareowners for
   financial reporting purposes are determined in accordance with federal income
   tax rules. Therefore, the sources of the Fund's distributions may be shown in
   the accompanying financial statements as from or in excess of net investment
   income or net realized gain on investment transactions, or as from paid-in
   capital, depending on the type of book/tax differences that may exist. A
   portion of the dividend income recorded by the Fund is from distributions by
   publicly traded REITs, and such distributions for tax purposes may also
   consist of capital gains and return of capital. The actual return of capital
   and capital gains portions of such distributions will be determined by formal
   notifications from the REITs subsequent to the calendar year-end.
   Distributions received from the REITs that are determined to be a return of
   capital are recorded by the Fund as a reduction of the cost basis of the
   securities held.

   At December 31, 2008, the Fund had a net capital loss carryforward of
   $7,060,199, which will expire in 2016 if not utilized.

   The tax character of current year distributions paid will be determined at
   the end of the current taxable year. The tax character of distributions paid
   during the year ended December 31, 2008, was as follows:





- -----------------------------------------------
                                           2008
- -----------------------------------------------
                                   
   Distributions paid from:
   Ordinary income                   $3,426,917
   Long-term capital gain                    --
   Return of capital                  2,170,453
- -----------------------------------------------
     Total                           $5,597,370
===============================================


  The following shows the components of distributable earnings on a federal
  income tax basis at December 31, 2008:





- -----------------------------------------------
                                          2008
- -----------------------------------------------
                              
   Distributable earnings:
   Capital loss carryforward     $ (7,060,199)
   Unrealized depreciation        (24,405,810)
- -----------------------------------------------
     Total                       $(31,466,009)
===============================================


   The difference between book basis and tax-basis unrealized depreciation is
   attributable to the tax deferral of losses on wash sales.


C. Fund Shares

   The Fund records sales and repurchases of its shares as of trade date.
   Pioneer Funds Distributor, Inc. (PFD), the principal underwriter for the Fund
   and a wholly owned indirect subsidiary of UniCredit S.p.A.


30    Pioneer Real Estate Shares | Semiannual Report | 6/30/09


   (UniCredit), earned $5,375 in underwriting commissions on the sale of Class A
   shares during the six months ended June 30, 2009.


D. Class Allocations

   Income, common expenses and realized and unrealized gains and losses are
   calculated at the Fund level and allocated daily to each class of shares
   based on their respective percentage of adjusted net assets at the beginning
   of the day. Distribution fees are calculated based on the average daily net
   asset value attributable to Class A, Class B and Class C shares of the Fund,
   respectively. Class Y shares are not subject to a distribution plan (see Note
   4). Shareowners of each class participate in all expenses and fees paid to
   the transfer agent, Pioneer Investment Management Shareholder Services, Inc.
   (PIMSS), for its services, which are allocated based on the number of
   accounts in each class and the ratable allocation of related out-of-pocket
   expenses (see Note 3).

   Distributions to shareowners are recorded as of the ex-dividend date.
   Distributions paid by the Fund with respect to each class of shares are
   calculated in the same manner and at the same time, except that Class A,
   Class B, Class C and Class Y can bear different transfer agent and
   distribution expense rates.


E. Securities Lending

   The Fund lends securities in its portfolio to certain broker-dealers or other
   institutional investors. When entering into a securities loan transaction,
   the Fund typically receives cash collateral from the borrower equal to at
   least the value of the securities loaned, which is invested in temporary cash
   investments. Credit Suisse, New York Branch, as the Fund's security lending
   agent, manages the Fund's securities lending collateral. The income earned on
   the investment of collateral is shared with the borrower and the lending
   agent in payment of any rebate due to the borrower with respect to the
   securities loan, and in compensation for the lending agent's services to the
   Fund. The Fund also continues to receive interest or payments in lieu of
   dividends on the securities loaned. Gain or loss on the value of the loaned
   securities that may occur during the term of the loan will be for the account
   of the Fund. The amount of the collateral is required to be adjusted daily to
   reflect any price fluctuation in the value of the loaned securities. The Fund
   has the right, under the lending agreement, to terminate the loan and recover
   the securities from the borrower with prior notice. The Fund will be required
   to return the cash collateral to the borrower and could suffer a loss if the
   value of the collateral, as invested, has declined.


                  Pioneer Real Estate Shares | Semiannual Report | 6/30/09    31


F. Repurchase Agreements

   With respect to repurchase agreements entered into by the Fund, the value of
   the underlying securities (collateral), including accrued interest, is
   required to be at least equal to or in excess of the value of the repurchase
   agreement. The collateral for all repurchase agreements is held in
   safekeeping in the customer-only account of the Fund's custodian or
   subcustodians. The Fund's investment adviser, Pioneer Investment Management,
   Inc. (PIM), is responsible for determining that the value of the collateral
   remains at least equal to the repurchase price.


2. Management Agreement

PIM, a wholly owned indirect subsidiary of UniCredit, manages the Fund's
portfolio. Management fees are calculated daily at the annual rate of 0.80% of
the Fund's average daily net assets. PIM pays a portion of the fee it receives
from the Fund to AEW Capital Management, L.P. as compensation for sub-advisery
services to the Fund.

In addition, under the management and administration agreements, certain other
services and costs, including accounting, regulatory reporting and insurance
premiums, are paid by the Fund. Included in "Due to affiliates" reflected on
the statement of Assets and Liabilities is $2,037 in management fees,
administrative costs and certain other fees payable to PIM at June 30, 2009.


3. Transfer Agent

PIMSS, a wholly owned indirect subsidiary of UniCredit, provides substantially
all transfer agent and shareowner services to the Fund at negotiated rates.

In addition, the Fund reimbursed PIMSS for out-of-pocket expenses related to
shareholder communications activities such as proxy and statement mailings,
outgoing phone calls and omnibus relationship contracts. For the six months
ended June 30, 2009, such out of pocket expenses by class of shares were as
follows:





- -------------------------------------------
Shareholder Communications:
- -------------------------------------------
                                 
 Class A                            $33,564
 Class B                             12,259
 Class C                              7,184
 Class Y                              1,084
- -------------------------------------------
   Total                            $54,091
===========================================


Included in "Due to affiliates" reflected on the Statement of Assets and
Liabilities is $39,999 in transfer agent fees and shareholder communications
expense payable to PIMSS at June 30, 2009.

4. Distribution Plan

The Fund has adopted a Distribution Plan pursuant to Rule 12b-1 of the
Investment Company Act of 1940 with respect to its Class A, Class B and Class C
shares. Pursuant to the Plan, the Fund pays PFD 0.25% of the average daily net
assets attributable to Class A shares as compensation for personal services
and/or account maintenance services or distribution services with regard to
Class A shares. Pursuant to the Plan, the Fund pays PFD 1.00% of the average
daily net assets attributable to Class B and Class C shares. The fee for Class
B and Class C shares consists of a 0.25% service fee and a 0.75% distribution
fee paid as compensation for personal services and/or account maintenance
services or distribution services with regard to Class B and Class C shares.
Prior to February 1, 2008, PFD was reimbursed under the Distribution Plan for
distribution expenses in an amount up to 0.25% of the average daily net assets
attributable to Class A shares. Included in "Due to affiliates" reflected on
the Statement of Assets and Liabilities is $695 in distribution fees payable to
PFD at June 30, 2009.

In addition, redemptions of each class of shares (except Class Y shares) may be
subject to a contingent deferred sales charge (CDSC). A CDSC of 1.00% may be
imposed on redemptions of certain net asset value purchases of Class A shares
within 18 months of purchase (within 12 months for purchases made on or after
April 1, 2009). Class B shares that are redeemed within five years of purchase
are subject to a CDSC at declining rates beginning at 4.0%, based on the lower
of cost or market value of shares being redeemed. Redemptions of Class C shares
within one year of purchase are subject to a CDSC of 1.00%, based on the lower
of cost or market value of shares being redeemed. Proceeds from the CDSC are
paid to PFD. For the six months ended June 30, 2009, CDSCs in the amount of
$6,647 were paid to PFD.


5. Expense Offset Arrangements

The Fund has entered into certain expense offset arrangements with PIMSS
resulting in a reduction in the Fund's total expenses due to interest earned on
cash held by PIMSS. For the six months ended June 30, 2009, the Fund's expenses
were reduced by $51 under such arrangements.


6. Line of Credit Facility

The Fund, along with certain other funds in the Pioneer Family of Funds (the
Funds), collectively participate in a $165 million committed, unsecured
revolving line of credit facility. Borrowings are used solely for temporary or
emergency purposes. The Fund may borrow up to the lesser of $165 million or the
limits set for borrowing by the Fund's prospectus and the 1940 Act. Interest on
collective borrowings is payable as follows: if the London Interbank Offered
Rate (LIBOR) on the related borrowing date is greater than or equal to the
Federal Funds Rate on such date, the loan bears interest at the LIBOR rate plus



                  Pioneer Real Estate Shares | Semiannual Report | 6/30/09    33


1.25% on an annualized basis, or if the LIBOR rate on the related borrowing
date is less then the Federal Funds Rate on such date, the loan bears interest
at the Federal Funds Rate plus 1.25% on an annualized basis. The Funds pay an
annual commitment fee for this facility. The commitment fee is allocated among
participating Funds based on an allocation schedule set forth in the credit
agreement. For the six months ended June 30, 2009, the Fund had no borrowings

 PIONEER FUNDS
            APPROVAL OF AUDIT, AUDIT-RELATED, TAX AND OTHER SERVICES
                       PROVIDED BY THE INDEPENDENT AUDITOR

                  SECTION I - POLICY PURPOSE AND APPLICABILITY

The Pioneer Funds recognize the importance of maintaining the independence of
their outside auditors. Maintaining independence is a shared responsibility
involving Pioneer Investment Management, Inc ("PIM"), the audit committee and
the independent auditors.

The Funds recognize that a Fund's independent auditors: 1) possess knowledge of
the Funds, 2) are able to incorporate certain services into the scope of the
audit, thereby avoiding redundant work, cost and disruption of Fund personnel
and processes, and 3) have expertise that has value to the Funds. As a result,
there are situations where it is desirable to use the Fund's independent
auditors for services in addition to the annual audit and where the potential
for conflicts of interests are minimal. Consequently, this policy, which is
intended to comply with Rule 210.2-01(C)(7), sets forth guidelines and
procedures to be followed by the Funds when retaining the independent audit firm
to perform audit, audit-related tax and other services under those
circumstances, while also maintaining independence.

Approval of a service in accordance with this policy for a Fund shall also
constitute approval for any other Fund whose pre-approval is required pursuant
to Rule 210.2-01(c)(7)(ii).

In addition to the procedures set forth in this policy, any non-audit services
that may be provided consistently with Rule 210.2-01 may be approved by the
Audit Committee itself and any pre-approval that may be waived in accordance
with Rule 210.2-01(c)(7)(i)(C) is hereby waived.

Selection of a Fund's independent auditors and their compensation shall be
determined by the Audit Committee and shall not be subject to this policy.

                 foundation to complete the

                 not performed by the Audit
                 firm, the scope of the Audit
                 Services would likely
                 increase.  The Services are
